NCC# Description
574 NV declaration should not be based on a CPT. Are you missing a 'cp'
modifier?[NCC#574]
Declare network variables using network variable types, and declare
configuration properties using configuration property types. For
configuration properties implemented as configuration network variables,
use configuration property types that reference a network variable type.
Do not declare network variables using configuration property types unless
you declare a configuration network variable.
575 The system timer interrupt is already used with a different interrupt task
[NCC#575]
You can only declare one interrupt task associated with the system timer
interrupt.
576 All available timer/counter interrupts are already used with different interrupt
tasks [NCC#576]
You can only declare up to two interrupt tasks associated with the
hardware timer or counter units.
577 All available I/O interrupts are already used with different interrupt tasks
[NCC#577]
You can only declare up to two interrupt tasks associated with I/O.
578 Parser error (unexpected semantic device type) [NCC#578]
579 This I/O device cannot trigger an interrupt task; use a supported timer/counter
configuration or declare an I/O interrupt instead [NCC#579]
Only the hardware timer and counter units can generate interrupts that
can be referenced through the I/O model, but you can reference all available
I/O pins in declarations of I/O interrupt tasks.
580 A single I/O interrupt cannot be triggered through both high and low levels; use
a single level trigger and define two I/O interrupts if needed [NCC#580]
581 Malformed system timer frequency value [NCC#581]
When specifying the periodic system timer’s frequency in the declaration of
a system timer interrupt task, you can describe the frequency as a floating-
point constant in typical C notation. The value of this constant describes
the requested timer frequency in Hertz. Optionally, you can use one of the
following postfix modifiers for readability: “Hz,” “kHz,” “MHz” or “GHz.”
Note those postfix modifiers are case-sensitive.
The following frequency definitions result in the same value: “1e3,” “1000,”
“1kHz,” “1e-3MHz,” “1000Hz”.
The NCC#581 error related to an unrecognized postfix modifier.
